YOUNGSTOWN, OHIQ PIVOTED WINDOW SASH Application filed December 31, 1929. Serial No. 417,788.

' or of an upper and lower sash of the window by rotative movement while providing for a vertical upward and downward movement of the respective upper and lower sashes.

Pursuant to a preferred form of my invention, the device comprises an upper and lower sash which are respectively mounted to, two slidably maintained support members to which each sash is pivotally secured.

A further object of the invention is to provide means for interlocking said window sash and support member in order to prevent moisture or dust from passing between said sash and support member.

A still further object of the invention is to provide means for holding said sash and support member under spring tension in order to prevent rattling of the sashes in relation to the support member or the support member in relation to grooves in which these '2 support members are slidably maintained.

A still further object of the invention is to provide means for holding the sash or sashes in a closed position in relation to these slidably maintained support members.

The main object for providing a device of this kind is to construct a sash arrangement which allows the sash or sashes to be rotated upon a pivot in order that the outside of the sash or sashes may be rotated inwardly so that the outside of the sash or glass secured therein may be washed and cleaned from the inside.

It will be obvious from the drawings and the following description that the cleaning I of the glass of the upper and lower sash may be maintained wholly from the interior of the window sash thus obviating the danger to life and limb of present day window cleaning and eliminating the liabilities entailed in present day window cleaning method. It also is obvious that when it is desired to replace a broken glass the operation of replacement may be attained without removing the sash, if desired, and wholly from the interior of the window casing.

It is also obvious that windows of ordinary type maybe equipped economically in houses already built, or may be installed in new buildings.

"With the foregoing and other view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of which is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein Figure l is a perspective view of the window frame containing an upper and lower window sash completely assembled therein. Figure 2 is a perspective view of one of the support members.

Figure 3 is an enlarged detailed perspective view of a stile of the window sash.

Figure 4 is an enlarged cross section taken on line H of Fig. 1.

Figure 5 is an enlarged cross section on line 55 of Fig. 1.

Figure 6 is a cross section on line 6-6 of Fig; 1 showing both window sashes in closed position and in an open position indicated by a dottedline.

By referring to the drawings it will be seen that I have provided an ordinary window frame 1. Into this window-frame l'there is positioned an uppersash 2 and a lower sash 3. The upper sash '2 and the lower sash 3 are similar and attached parts to each are similar.

By referring to Fig. 3 it will' be seen that each stile 4 of the sashes 2 and 3 is provided with oppositely disposed lateral flanges 5 and oppositely disposed lateral grooves 6. Each groove 6 having its inner wall 7 formed on a common plane 8.

By-referring to Fig. 2'it will be seen that there is provided a slidably, maintained support member 9, each sash is provided with a pair of these slidably maintained support members 9. An outer portion 10 of each of said slidably maintained support members 9 function within an ordinary slide way 11 of objects in the frame 1. Each slidably maintained support member 9 is provided with oppositely disposed lateral flanges 12 and oppositely disposed lateral grooves 13, in order that the sash and slidably maintained support member may be securely closed without increasing the width of the sash and slidably maintained support member whether opened or closed. Centrally located upon an inner surface 1% there is provided a rectangular spring friction member 15 provided with a slightly upwardly curved edge 16. This spring friction member 15 is provided with a central opening 17 for the reception of the pivot screw 18, in assembling the device the rectangular spring friction member 15 is placed so that the central opening 17 is in alinement with the opening 19 formed in the stile l. The pivot screw 18 is now placed so as to function through the central opening 17 and into the opening 19. (See Fig. 5.) It will be seen that the oppositely disposed lateral flange 5 now functions within the oppositely disposed lateral grooves 13 and that the oppositely disposed lateral flange 12 functions within the oppositely disposed lateral grooves 6. In order that the sashes 2 and 8 are held in a closed position when closed there is provided an orifice 20 positioned on the upper inner end of each of the slidably maintained support members 9. Each sash is provided with a spring tension dog 21 functioning within the orifice 20 when the sash is in a closed position.

By referring to Fig. 2 it will be seen that a lower end of an upper groove of the op positely disposed lateral grooves terminates in a water pocket 22 which is provided with a water channel 23 for the purpose of preventing water from finding its way to the interior of the sashes and connecting parts.

It will be readily understood that when the rectangular spring friction member 15 is functioning between the stile 4 and the slidably maintained support member '9, the same will provide a dual function in preventing rattling between the slide way 11 of the frame 1 and the parts slid within. It is also evident that when the sashes 2 and 3 is in an open position the friction exerted by the means of the rectangular spring friction member 15 will tend to hold the sash in position desired.

What I claim is 1. In a window structure, a sash, a pair of slidable support members disposed one on each side of the sash, a pivotal connection between each sash stile and an adjacent support member whereby said sash may be rotated on a horizontal axis from and to closed position, complemental formations on the related stiles and support members interfitting when the sash is closed, and a spring plate secured to each member between the adjacent surfaces of the latter and its related stile, said plate pressing the stile and member away from each other when the sash is closed to prevent rattling and having its free end curved away from its related member for direct cooperation with the adjacent stile to provide a friction lock to secure the sash in various angular positions about the pivotal connections.

2. In a window structure, a sash, a pair of slidable support members disposed one on each side of the sash, a pivotal connection between each sash stile and an adjacent support member whereby said sash may be rotated on a horizontal aXis from and to closed position, said stiles and support members each having oppositely disposed upper and lower tongue and groove formations with the formation of each stile interfitting with respective formations of its related member when the sash is closed, and a drain at the lower end of the upper formation on each member, said drain being formed of a pocket positioned on the member to receive water from the tongue and groove surface of its related formation and a downwardly inclined channel leading from the pocket through the outer face of the related stile.

In testimony whereof I afliX my signature.

SAMUEL IRVIN BAER.
